I did variations on both patterns.
For my shorts I reduced about ½ cm on both sides, and I didn’t left any seam
allowance (that’s what she proposes for a size M). They are still a bit too
loose for me, but it’s ok since I wanted them to be comfy.

For Bubu’s shorts, I reduced 3 cm
from the waist, and 0.7 cm from each side. And I didn’t left seam allowance
again. I think she will be wearing them next year too.

I did the pockets, the waistband and
the bottom hem with jersey, recycling an old T-shirt. It was handy doing it
this way, especially for the pockets, because I could sew them directly (only
the opening has a hem).

Because the jersey was no longer
that stretch and I didn’t have enough of it, I did the waistband like Mónica
from “Rojo ababol” proposed, threading an elastic through it.

And by the way, I drew a pocket for
the mini version, because it was not there (although Dawn proposed thousand
pocket alternatives).
